Can I edit a dbase in a Truecrypt container with 00base, under Ubuntu 8.04.1 64 bit?

I've tried to get a dbase file, which resides in a Truecrypt 6.0a container, into edit mode (in base 2.4) with both Hardy Heron and openSuse 11.0 (the latter which I ran screaming from last week, BUGS!!!). The database connects, I can create the form and open the database, but it stays in read-only mode (and the pencil "edit mode" icon stays grayed out). I looked for a macro solution (to change driver privileges), but the one I found is labeled as not for openoffice versions after 2.0.
I'm guessing I'll have to install some other crypt file, if the edit mode won't work with Truecrypt.

The real answer is to upgrade your kernel to at least 2.6.25. At least that's what the True Crypt people say on their forums page. They claim that an error in previous kernels is causing i/o problems with their product from v5.0 and later.

Since I don't want to upgrade my kernel from source I have taken a different workaround, but this workaround WON'T WORK FOR V6.0 OF TRUE CRYPT. This workaround only works for v5.0a and v5.1a of True Crypt. I booted System Rescue CD which has v4.3 of True Crypt installed. I created the encrypted partition using that version and then booted my Kubuntu or PCLOS. (I use True Crypt on both systems.) Then I mounted the encrypted partition onto a loop device using the True Crypt GUI and then created a file system on the loop device. Note also that you cannot use ext3 with this method. The xfs file system will create the file system but ext3 hangs while it is creating the file system with a blockin i/o on the entire disk. This eventually causes other processes to hang when they attempt to access the disk and sooner or later most of the processes on your system are hung.

If you use this workaround be aware that creating the encrypted partition or container file using v4.3 of True Crypt will prevent you from using the new features in True Crypt. That's probably why it works.
